Clock performance on Windows Mobile

Using the previous article "Rotating images from any angle on Windows Mobile", you can achieve a brilliant effect. Every time we need three pictures, three PNG pictures, one for the hour, one for the hour, and one for the minute.

For example:

 

 

 

 

The image is taken from Android.

The implementation code is as follows:

Void drawclock (HDC, rect RC) <br/>{< br/> systemtime; </P> <p> getlocaltime (& systemtime ); </P> <p> iimage * pcurclockhour = NULL; <br/> iimage * pcurclockmin = NULL; <br/> imageinfo imdialinfo; <br/> imageinfo imhourinfo; <br/> imageinfo immininfo; </P> <p> lpbytephourbuf = NULL; <br/> lpbyte pminbuf = NULL; <br/> point ptclockcenter; <br/> rect rcdial; <br/> rect rchour; <br/> rect rcmin; </P> <p> getclientrect (g_hwnd, & rc ); </P> <p> HDC hdcoffset = createcompatibledc (HDC); <br/> hbitmap hbmpoffset = createcompatiblebitmap (HDC, RC. right-RC. left, RC. bottom-RC. top); <br/> SelectObject (hdcoffset, hbmpoffset); <br/> fillrect (hdcoffset, & rc, (hbrush) getstockobject (white_brush )); <br/> // load the image from the JPG file. </P> <p> If (pclockdial = NULL) <br/> pimgfactory-> createimagefromfile (text ("// clockgoog_dial.png"), & pclockdial ); <br/> If (pclockhour = NULL) <br/> pimgfactory-> createimagefromfile (text ("// clockgoog_hour.png"), & pclockhour ); <br/> If (pclockmin = NULL) <br/> pimgfactory-> createimagefromfile (text ("// clockgoog_minute.png"), & pclockmin ); </P> <p>/* <br/> If (pclockdial = NULL) <br/> pimgfactory-> createimagefromfile (text ("// clockdroid2_dial.png "), & pclockdial); <br/> If (pclockhour = NULL) <br/> pimgfactory-> createimagefromfile (text ("// clockdroid2_hour.png"), & pclockhour ); <br/> If (pclockmin = NULL) <br/> pimgfactory-> createimagefromfile (text ("// clockdroid2_minute.png"), & pclockmin ); <br/> */<br/> pclockdial-> getimageinfo (& imdialinfo); <br/> rcdial. left = (RC. right-RC. left)-imdialinfo. width)/2 + RC. left; <br/> rcdial. top = (RC. bottom-RC. top)-imdialinfo. height)/2 + RC. top; <br/> rcdial. right = rcdial. left + imdialinfo. width; <br/> rcdial. bottom = rcdial. top + imdialinfo. height; </P> <p> ptclockcenter.
